Peavey ICS 4200 user manual Attenuation in dB, Level Controls, Detent

The output of each module may be assigned to any channel and in any combination of channels. To assign the output of Module 1 to an amplifier channel(s)‚ simply slide the appropriate switch in the upper bank of switches to the ON position (right). Likewise‚ to assign the output of Module 2 to an amplifier channel(s)‚ slide the appropriate switch in the lower bank of switches to the ON position (right).

When selecting these switches‚ caution should be taken to ensure the front panel channel level controls are fully counter-clockwise or the amplifier is powered off. This will help prevent any damage to the loudspeaker system if there are high signal levels at the module inputs.

Caution: MMA™ plug-in modules should not be inserted or removed while amplifier is turned on.

Level Controls

Attenuation in dB

The signal level for each input can be attenuated by adjusting the 21-detent front panel level control. The table at right shows the amount of attenuation in dB for each detent.

Note: Attenuation amounts shown may vary ±10%.
